COVID-19 impact on post-traumatic stress symptoms in burning mouth syndrome: A multicentric study.

OBJECTIVES: This study investigates the psychological impact of COVID-19 on burning mouth syndrome (BMS) patients. It focuses on comparing post-traumatic stress symptoms (PTSS), post-traumatic growth (PTG), and resilience between BMS patients and Controls. METHODS: A total of 100 BMS patients and 100 Controls from five Italian centers participated in this observational cross-sectional study. They completed several assessments, including the General Health Questionnaire, Depression Anxiety and Stress Scale, Insomnia Severity Index, National Stressful Events Survey Short Scale, Impact of Event Scale-Revised, Post Traumatic Growth Inventory Short Form, and Connor-Davidson Resilience Scale. RESULTS: BMS patients had significantly higher stress, anxiety, and depression (DASS-21 score) and post-traumatic stress symptoms (IES-R-6 score), particularly in terms of intrusive thoughts. They showed lower post-traumatic growth (PTGI-SF score) compared to Controls. The resilience scale (CDRS-10) was a key predictor of PTG in both groups, explaining a significant variance in PTGI-SF scores. CONCLUSIONS: BMS patients experienced heightened post-traumatic stress, stress, anxiety, and depression during the COVID-19 pandemic, with reduced post-traumatic growth. This highlights the need to prioritize their psychological well-being, focusing on stress management and fostering post-traumatic growth in challenging times.

Preventive versus curative photobiomodulation for oral mucositis in patients with multiple myeloma undergoing hematopoietic stem cell transplantation: which approach is more effective?

PURPOSE: There is increasing evidence that photobiomodulation (PBM) therapy is both an effective and safe approach in hematopoietic stem cell transplantation (HSCT) for both prevention and management of oral mucositis (OM), but its use in clinical practice is still limited and the timing of application is under discussion. The aim of this retrospective study was to evaluate possible differences between patients treated either with preventive or curative PBM therapy. METHODS: The retrospective case series included 24 patients suffering from multiple myeloma who underwent the same conditioning and transplantation protocol. Patients were treated either with preventive PBM starting from the first day of conditioning up to two days post-HSCT or with curative PBM (starting at OM onset for four consecutive days). OM score, pain, and functional parameters were recorded. RESULTS: All patients developed OM. Preventive PBM was significantly more effective in reducing OM severity (p < 0.0001) and pain (p < 0.0001) post-HSCT than curative PBM. Furthermore, we found a lower number of patients reporting discomfort in all subjective parameters (pain during swallowing, chewing, and speaking) in the preventive PBM group. No adverse events related to PBM therapy were recorded in both groups. CONCLUSION: The timing for PBM therapy in patients undergoing HSCT is crucial: when started on the first day of conditioning, it significantly reduces both pain and OM severity, providing an important benefit also in subjective oral functions such as speaking, swallowing, and chewing, thus increasing the overall adherence to the oncological therapies.

Changes in mandibular radiomorphometric indices in osteoporosis patients treated with denosumab: a retrospective case-control study.

BACKGROUND: Radiomorphometric indices measured on Dental Panoramic Radiography (DPR) can reflect Bone Mineral Density (BMD). The aim of our study is to evaluate changes in DPR radiographic markers in patients undergoing antiresorptive therapy with denosumab and correlate them to BMD and serum bone turnover markers (BTM). METHODS: We evaluated two radiomorphometric indices: Mandibular Cortical Width (MCW) and Panoramic Mandibular Index (PMI), in patients undergoing antiresorptive therapy with denosumab at T0 (before starting the therapy) and at T1 (after 12 months), comparing results with a control group of healthy patients who performed two DPRs at a one-year time distance. Correlation analysis was performed in the denosumab group, as well as ROC curves were obtained for both indices. RESULTS: The study included 18 patients and 21 controls according to specific inclusion and exclusion criteria, matched by gender and age. Both MCW and PMI were significantly lower at T0 in the denosumab group, consistently with lower BMD. MCW showed significant correlation with femoral and lumbar DEXA and was significantly lower in patients with osteoporosis compared to osteopenia. Only PMI index increased significantly in the denosumab group from T0 to T1. After one year (T1), there weren't any differences between patients and controls for both indices. No significant correlations were found with BTMs. Sensitivity and specificity for MCW and PMI were also calculated. CONCLUSIONS: Our results show how CMW shows sufficient sensitivity and specificity to be used as a radiographic marker to screen and intercept patients with osteoporosis. PMI seems to be able to reflect changes in response to antiresorptive therapy with denosumab. Further studies are needed to confirm our hypothesis.

Dental Treatment in Special Needs Patients and Uncooperative Young Children: A Retrospective Study.

Background and Objectives: Special Needs Patients (SNPs) and young non-collaborative children are more predisposed to develop oral pathologies due to poor collaboration and scarce access to dental treatment. The aim of this retrospective study was to analyze a sample of SNPs who received dental treatments either under general anesthesia (GA) or deep sedation (DS) over a period of 6 years. The number and type of procedure were analyzed. Materials and Methods: In total, 131 patients were included and mostly (>90%) treated under GA. Patients were either uncooperative and phobic (Group 1) or affected by mental, behavioral, and neurological disorders (Group 2), diseases of the nervous system (Group 3), or developmental anomalies (Group 4). Results: Patients in Group 2 required more invasive dental treatments than those in the other groups. Therapies were mainly preventive and restorative, except in Groups 3 and 4, where extractions were more frequent. The type of dental treatment significantly varied according to age and systemic condition. Only 5.3% of the patients needed a second intervention, despite only 17.6% of patients respecting the scheduled follow-up. Conclusions: Treatment under GA is effective, but the poor adherence to follow-ups and the risk of reintervention should be contrasted by improving the perception by parents/guardians of the importance of oral hygiene and periodic visits.

Advancements in Understanding and Classifying Chronic Orofacial Pain: Key Insights from Biopsychosocial Models and International Classifications (ICHD-3, ICD-11, ICOP).

In exploring chronic orofacial pain (COFP), this review highlights its global impact on life quality and critiques current diagnostic systems, including the ICD-11, ICOP, and ICHD-3, for their limitations in addressing COFP's complexity. Firstly, this study outlines the global burden of chronic pain and the importance of distinguishing between different pain types for effective treatment. It then delves into the specific challenges of diagnosing COFP, emphasizing the need for a more nuanced approach that incorporates the biopsychosocial model. This review critically examines existing classification systems, highlighting their limitations in fully capturing COFP's multifaceted nature. It advocates for the integration of these systems with the DSM-5's Somatic Symptom Disorder code, proposing a unified, multidisciplinary diagnostic approach. This recommendation aims to improve chronic pain coding standardization and acknowledge the complex interplay of biological, psychological, and social factors in COFP. In conclusion, here, we highlight the need for a comprehensive, universally applicable classification system for COFP. Such a system would enable accurate diagnosis, streamline treatment strategies, and enhance communication among healthcare professionals. This advancement holds potential for significant contributions to research and patient care in this challenging field, offering a broader perspective for scientists across disciplines.

Ozone treatment combined with sodium fluoride for the treatment of dentin hypersensitivity: an exploratory study.

BACKGROUND: Dentin hypersensitivity is one of the most common complains faced by dental professionals, and there is still lack of consensus for the most effective treatment approaches. The aim of the present study was to evaluate the efficacy of ozone therapy combined with sodium fluoride in reducing pain associated with dental hypersensitivity, compared to a paint-on adhesive desensitizing agent. METHODS: The study included 20 patients (131 teeth), selected according to specific inclusion criteria and divided into two groups according to the type of desensitizing therapy (ozone with sodium fluoride or paint-on adhesive). The efficacy of both treatments were evaluated recording pain for each treated tooth immediately after treatment, after 1 month and after 6 months using a Numeric Rating Scale (NRS). Subjective parameters were also recorded: patients were asked to report whether they experienced pain caused by air, teeth brushing, cold and hot topical stimuli (present/absent). RESULTS: In both groups, pain values significantly decreased over time. Six months after treatment we registered significantly lower pain values in the ozone-treated group compared with the adhesive group and the mean percentage of NRS reduction from was significantly higher in the ozone-treated group. We did not register significant differences in subjective pain-related parameters between groups. CONCLUSIONS: The results of this exploratory study were aimed at exploring the combined effect of ozone with natrium fluoride, which was before described only in vitro. With the limitation of the sample size, our results suggest that this approach provides a pain reduction that was comparable to the paint-on adhesive.

Knowledge and awareness of oral cancer: A cross-sectional survey in Trieste, Italy.

The aim of the study was to verify the knowledge on oral cancer and to assess possible differences in awareness and information basing on different demographic and subject-related factors. An anonymous survey was provided to 750 random subjects using online-based questionnaires. Statistical analysis was performed in order to evaluate the influence of demographic variables (gender, age, education) on knowledge of oral cancer and its risk factors. 68.4% of individuals knew about the existence of oral cancer, mostly from media and family/friends. Awareness was significantly influenced by gender and higher education, but not by age. Most participants recognized smoking as a risk factor, but alcohol abuse and sunlight exposure are less known, especially among less educated subjects. On the contrary, our study shows a diffusion of false information: more than 30% of the participants indicated the possible role of amalgam fillings in oral cancer onset, independently of gender, age or education. The results of our study suggest the need for oral cancer awareness campaigns, where school and healthcare professionals should be actively involved in promoting, organizing and finding methods to monitor the medium and long-term efficacy with proper methodological quality.

Anxiety and depression in keratotic oral lichen planus: a multicentric study from the SIPMO.

OBJECTIVES: Oral lichen planus with exclusive keratotic reticular, papular, and/or plaque-like lesions (K-OLP) is a clinical pattern of OLP that may be associated with a complex symptomatology and psychological alteration. The aim of the study was to evaluate the prevalence of anxiety (A) and depression (D) in patients with K-OLP, analyzing the potential predictors which can affect mental health status. METHODS: Three hundred K-OLP patients versus 300 healthy controls (HC) were recruited in 15 Italian universities. The Numeric Rating Scale (NRS), Total Pain Rating Index (T-PRI), and Hamilton Rating Scales for Depression and for Anxiety (HAM-D and HAM-A) were administered. RESULTS: The K-OLP patients showed statistically higher scores in the NRS, T-PRI, HAM-D, and HAM-A compared with the HC (p-value < 0.001**). A and D were found in 158 (52.7%) and 148 (49.3%) K-OLP patients. Strong linear correlations were identified between HAM-A, HAM-D, NRS, T-PRI, and employment status and between HAM-D, HAM-A, NRS, T-PRI, employment status, and female gender. Multivariate logistic regression revealed that HAM-D and HAM-A showed the greatest increase in the R2 value for A and D in the K-OLP patients, respectively (DR2 = 55.5% p-value < 0.001**; DR2 = 56.5% p-value < 0.001**). CONCLUSIONS: The prevalence of A and D is higher in the K-OLP patients compared with the HC, also found in K-OLP subjects without pain, suggesting that the processing of pain may be in a certain way independent of the processing of mood. CLINICAL RELEVANCE: Mood disorders and pain assessment should be carefully performed in relation to K-OLP to obtain a complete analysis of the patients.

Histopathology of oral lichen planus and oral lichenoid lesions: An exploratory cross-sectional study.

OBJECTIVE: To better characterize the histopathology of oral lichen planus and oral lichenoid lesions and to highlight the differences between them in order to support the clinician in the diagnostic and therapeutic management of such conditions. SUBJECTS AND METHODS: Fifty-five patients, clinically diagnosed with oral lichen planus (n = 25) or oral lichenoid lesions (n = 30), were consecutively enrolled in the present study. Subsequently, one blind pathologist reviewed all the biopsy specimens of enrolled subjects following a specific protocol to provide a detailed histopathological description. Demographic, anamnestic, and clinical data were also recorded from all the participants. Patients' data were analysed and compared using the chi-squared test, to provide distinguishing features between the studied conditions. RESULTS: We found a higher and statistically significant number of eosinophils in the oral lichenoid lesions compared with the oral lichen planus group (p < 0.01), an equally promising result was seen regarding plasma cells, which were more represented (p = 0.05) in the oral lichenoid lesions than in the oral lichen planus cases. No statistically significant differences were detected in demographic, anamnestic and clinical data. CONCLUSION: A mixed lichenoid inflammatory infiltrate, consisting of eosinophils and plasma cells, could be used as reliable histological features for the diagnosis of oral lichenoid lesions, as long as compared with findings obtained from the patients' history and clinical examination.

Oral Problems in Oncology Patients Undergoing Chemotherapy for Solid Tumors: A Prospective Observational Study.

PURPOSE: Oral problems in a group of oncological patients undergoing chemotherapy (CT) for solid tumors have been examined. Incidence and severity of patients' self-reported oral problems have been evaluated along their interaction with age, gender, tumor diagnosis and stage, presence of mestastasis, CT agent type, and number of CT cycle. We also analyzed the presence of paraesthesia and anaesthesia and their predisposing factors associated with clinical and treatment-related variables. METHODS: Patients were asked to fill in a questionnaire to evaluate the onset and the intensity of oral and perioral pain, oral mucositis, salivary gland hypofunction, dysgeusia, dysphagia, dysphonia, and sensitivity neuropathy (paraesthesia or dysaesthesia) since the last CT infusion. We also investigated which types of medications have possibly been used and who recommended it, as well as patients' degree of awareness about the possibility of oral problems arising during CT. RESULTS: We recruited 194 patients and obtained 491 questionnaires. We found that a metastatic disease was a risk factor for OM (OR 2.02, p = 0.026) and salivary gland hypofunction (OR 1.66, p = 0.042) and that platinum agents, compared to mitotic inhibitors, increased the risk of developing salivary gland hypofunction (OR 2.16, p = 0.013), dysphagia (OR 3.26, p = 0.001), and anaesthesia (OR 5.16, p = 0.041). Young age was a slight protective factor for most symptoms. The 80% of enrolled patients were informed by the oncologist about possible oral problems arising during CT. CONCLUSIONS: Our study highlighted the importance of collecting observational data from the patients' perspective on oral problems arising during the routine oncology practice, across a range of solid tumors and CT regimens. The relevance of these findings focused on the key role of the multidisciplinary team in advising the patients on the possible occurrence of oral problems, also by recommending their management.

Where do you live? North versus Central-South differences in relation to Italian patients with oral lichen planus: a cross-sectional study from the SIPMO (Italian Society of Oral Pathology and Medicine).

BACKGROUND: Oral lichen planus (OLP) is an immune-mediated inflammatory chronic disease of the oral mucosa, with different patterns of clinical manifestations which range from keratotic manifestations (K-OLP) to predominantly non-keratotic lesions (nK-OLP). The aim of the study was to analyze the differences in the clinical, psychological profile and symptoms between Italian patients of the North and Central-South with K-OLP and nK-OLP. METHODS: 270 K-OLP and 270 nK-OLP patients were recruited in 15 Italian universities. The Numeric Rating Scale (NRS), Total Pain Rating Index (T-PRI), Hamilton Rating Scales for Depression and for Anxiety (HAM-D and HAM-A), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS) were administered. RESULTS: The Central-South K-OLP (CS-K-OLP) patients reported a higher frequency of pain/burning compared with the K-OLP patients of the North (N-K-OLP) with higher scores in the NRS and T-PRI (p value < 0.001**). The CS-K-OLP and the CS-nK-OLP patients showed higher scores in the HAM-D, HAM-A, PSQI and ESS compared with the Northern patients (p value < 0.001**). Multivariate logistic regression revealed that the NRS and T-PRI showed the greatest increase in the R2 value for the CS-K-OLP (DR2 = 9.6%; p value < 0.001**; DR2 = 9.7% p value < 0.001**; respectively) and that the oral symptoms (globus, itching and intraoral foreign body sensation) and PSQI showed the greatest increase in the R2 value for the CS-nK-OLP (DR2 = 5.6%; p value < 0.001**; DR2 = 4.5% p value < 0.001** respectively). CONCLUSIONS: Pain and mood disorders are predominant in patients with OLP in the Central-South of Italy. Clinicians should consider that the geographical living area may explain the differences in oral symptoms and psychological profile in OLP.

Assessment of sleep disturbance in oral lichen planus and validation of PSQI: A case-control multicenter study from the SIPMO (Italian Society of Oral Pathology and Medicine).

BACKGROUND: The wellbeing of oral lichen planus patients (OLPs) may be strongly influenced by a poor quality of sleep (QoS) and psychological impairment. The aims were to analyze the prevalence of sleep disturbance, anxiety, and depression in OLPs and to validate the Pittsburgh Sleep Quality Index (PSQI) in OLPs. METHODS: Three hundred keratotic OLPs (K-OLPs), 300 with predominant non-keratotic OLP (nK-OLPs), and 300 controls were recruited in 15 Italian universities. The PSQI, Epworth Sleepiness Scale (ESS), Hamilton Rating Scales for Depression and Anxiety (HAM-D and HAM-A), Numeric Rating Scale (NRS), and Total Pain Rating Index (T-PRI) were administered. RESULTS: Oral lichen planus patients had statistically higher scores than the controls in the majority of the PSQI sub-items (p-values < 0.001**). Moreover, OLPs had higher scores in the HAM-D, HAM-A, NRS, and T-PRI (p-values < 0.001**). No differences in the PSQI sub-items' scores were found between the K-OLPs and nK-OLPs, although nK-OLPs suffered from higher levels of anxiety, depression, and pain (p-values: HAM-A, 0.007**, HAM-D, 0.009**, NRS, <0.001**, T-PRI, <0.001**). The female gender, anxiety, depression (p-value: 0.007**, 0.001**, 0.020*) and the intensity of pain, anxiety, and depression (p-value: 0.006**, <0.001**, 0.014*) were independent predictors of poor sleep (PSQI > 5) in K-OLPs and nK-OLPs, respectively. The PSQI's validation demonstrated good internal consistency and reliability of both the total and subscale of the PSQI. CONCLUSIONS: The OLPs reported an overall impaired QoS, which seemed to be an independent parameter according to the regression analysis. Hence, clinicians should assess QoS in OLPs and treat sleep disturbances in order to improve OLPs management.

What do we learn from the clinical and biological evaluation of the oral cavity in centenarians?

The number of centenarians is rapidly increasing worldwide and so are the studies on this segment of the population. A general consensus in the literature is that healthy longevity is an outcome of multiple factors, but the interrelationship between good oral health and healthy aging remains not fully understood. As part of the "CaT: Centenari a Trieste" study, a population-based cohort study set in Trieste, Italy, we report here the results of subjective self-reported oral health parameters and objective clinical and biological oral variables and their association with cognitive impairment in 25 centenarians enrolled in the study from September 2017 to May 2019. Oral health-related variables were recorded by means of a self-evaluation questionnaire and a comprehensive oral examination of teeth, prostheses and mucosae conducted by a trained dentist. In addition, 6-n-propylthiouracil (PROP) taste perception and salivary oxidative stress markers, specifically the Total Oxidative Status and Ferric Reducing Ability of Saliva, were measured. Finally, the oral data obtained were compared with the presence or absence of dementia in the enrolled subjects. The centenarians included in our study were generally satisfied with their oral health. Among the causes of discomfort, the most prevalent were difficulties in chewing and biting, with few subjects describing a correlation between their oral health and psycho-social issues. We evaluated possible relations of clinical and biological variables to the likelihood of being demented and did not find significant associations. We found a higher though not statistically significant mean salivary flow and antioxidant capacity of saliva in non-demented subjects. When evaluating the PROP taste perception profile, we found a higher proportion of supertasters compared with previous studies and different taste perception profiles according to dementia. Despite the relatively small number of participants, we believe that our study contributes to a better understanding of the clinical and biological profile of the oral cavity in subjects aged over 100 years, encouraging the inclusion of a comprehensive evaluation of the oral cavity in centenarian studies performed worldwide.

Psychological profile and unexpected pain in oral lichen planus: A case-control multicenter SIPMO studya.

OBJECTIVES: To analyze psychological profiles, pain, and oral symptoms in patients with oral lichen planus (OLP). MATERIALS AND METHODS: 300 patients with keratotic OLP (K-OLP; reticular, papular, plaque-like subtypes), 300 patients with predominant non-keratotic OLP (nK-OLP; erythematosus atrophic, erosive, ulcerative, bullous subtypes), and 300 controls were recruited in 15 universities. The number of oral sites involved and oral symptoms were recorded. The Numeric Rating Scale (NRS), Total Pain Rating Index (T-PRI), Hamilton Rating Scales for Depression and for Anxiety (HAM-D and HAM-A), Pittsburgh Sleep Quality Index (PSQI), and Epworth Sleepiness Scale (ESS) were administered. RESULTS: The OLP patients, especially the nK-OLP, showed higher scores in the NRS, T-PRI, HAM-D, HAM-A and PSQI compared with the controls (p-value < .001** ). A positive correlation between the NRS, T-PRI, HAM-A, HAM-D, and PSQI was found with the number of oral symptoms and number of oral sites involved. Pain was reported in 67.3% of nK-OLP and 49.7% of K-OLP cases with poor correspondence between the site of lesions and the site of the symptoms. CONCLUSIONS: Mood disorders are frequently associated with OLP with an unexpected symptomatology correlated with the number of oral symptoms and with the extension of disease suggesting a peripheral neuropathy.

Antimicrobial activity of amphiphilic nanomicelles loaded with curcumin against Pseudomonas aeruginosa alone and activated by blue laser light.

The aim of this work was to assess the antimicrobial efficacy on Pseudomonas aeruginosa of nanomicelles loaded with curcumin (CUR) alone and activated by blue laser light in an antimicrobial photodynamic therapy (APDT) approach. First, free CUR in liquid suspension and loaded in three amphiphilic nanomicelles (CUR-DAPMA, CUR-SPD and CUR-SPM) were tested both on bacteria and keratinocytes. While free CUR exerted limited efficacy showing moderate cytotoxicity, a strong inhibition of bacterial growth was obtained using all three nanosystems without toxicity on eukaryotic cells. CUR-SPM emerged as the most effective, and was therefore employed in APDT experiments. Among the three sublethal blue laser (λ 445 nm) protocols tested, the ones characterized by a fluence of 18 and 30 J/cm2 further decreased the antimicrobial concentration to 50 nM. The combination of blue laser APDT with CUR-SPM nanomicelles results in an effective synergistic activity that represents a promising novel therapeutic approach on resistant species.

Photobiomodulation modulates inflammation and oral microbiome: a pilot study.

INTRODUCTION: Oral mucositis (OM) is a severe side effect in patients undergoing anticancer therapies, which negatively impacts on their quality of life often leading to either the interruption of the therapy. Photobiomodulation (PBM) is emerging as an effective strategy allowing a faster wound healing. OBJECTIVES: This pilot study aims at verifying whether PBM modulates the inflammatory response in patients and its effect on the oral microbiome composition. MATERIALS AND METHODS: Buccal swabs were collected from four patients affected by OM, both on ulcerated and clinically healthy areas, before and on the last day of PBM therapy, as well as on the first day after treatment discontinuation. The concentration of 38 cytokines and the composition of oral microbiome were measured. RESULTS: Most of the pro-inflammatory cytokines were reduced, whereas anti-inflammatory cytokines resulted up-regulated by PBM. In addition, PBM influenced the composition of oral microbiome, by decreasing the amount of pathogenic species and promoting the growth of commensal bacteria. These changes were even more evident when separately analysing patients who clinically responded to PBM and the only patient who did not respond. CONCLUSIONS: PBM reduces inflammatory burden in patients affected by OM and positively influences the composition of the oral microbiome.

Medication-Related Osteonecrosis of Jaws (MRONJ) Prevention and Diagnosis: Italian Consensus Update 2020.

The Medication-Related Osteonecrosis of Jaws (MRONJ) diagnosis process and its prevention play a role of great and rising importance, not only on the Quality of Life (QoL) of patients, but also on the decision-making process by the majority of dentists and oral surgeons involved in MRONJ prevention (primary and secondary). The present paper reports the update of the conclusions from the Consensus Conference-held at the Symposium of the Italian Society of Oral Pathology and Medicine (SIPMO) (20 October 2018, Ancona, Italy)-after the newest recommendations (2020) on MRONJ were published by two scientific societies (Italian Societies of Maxillofacial Surgery and Oral Pathology and Medicine, SICMF and SIPMO), written on the inputs of the experts of the Italian Allied Committee on ONJ (IAC-ONJ). The conference focused on the topic of MRONJ, and in particular on the common practices at risk of inappropriateness in MRONJ diagnosis and therapy, as well as on MRONJ prevention and the dental management of patients at risk of MRONJ. It is a matter of cancer and osteometabolic patients that are at risk since being exposed to several drugs with antiresorptive (i.e., bisphosphonates and denosumab) or, more recently, antiangiogenic activities. At the same time, the Conference traced for dentists and oral surgeons some easy applicable indications and procedures to reduce MRONJ onset risk and to diagnose it early. Continuous updating on these issues, so important for the patient community, is recommended.

Self-perception and physician's awareness on early detection of tongue cancer: experience of the Oral Medicine Unit of Trieste.

BACKGROUND: The objective of this retrospective study was to characterize the outpatient oral medicine referral pattern for tongue lesions with particular emphasis on cancer. METHODS: Records of patients referred to the Oral Medicine department for any tongue lesions needing biopsy between 2009 and 2016 were retrospectively analyzed. All cases diagnosed as tongue cancer were screened for medical history, referral pattern, treatment/diagnosis/follow-up. RESULTS: Among 266 patients, 39 were diagnosed with cancer, 43.6% were smokers and 10.3% alcohol consumers, 38.5% felt pain, 53.8% noticed the lesion or felt its presence, 46.2% were referred from another specialist. For people aware or informed of the lesion. the mean time waited before consultation was 7.9 months. In 53.8% of cases, narrow-band-imaging guided the biopsy. In 29 patients, biopsy was performed the day of the visit. Patients were referred from dentists (42.1%), Primary-care-Physician (10.5%), Emergency-Dental-Unit (7.9%), Radiotherapist (7.9%), Otolaryngologist (7.9%), Dermatologist (26%), infectious diseases unit (2.6%), auto-referral in 18.4%. Lesion was defined by referring doctor as "suspicious" (13.1%), white (10.5%), vegentans (5.3%), Lichen-like (5.3%), ulcerative (2.6%), Tumoral (26.3%), Bollous (2.6%). An unweighted Kappa Value of 0.024, assessed low concordance between referral diagnosis and diagnosis performed by the Oral Medicine specialist before the biopsy. CONCLUSIONS: Patients are not always aware of the risk of oral cancer. Accurate information should be provided to patients as well as to specialists rather than just dentists as regard as the risk factors for oral cancer, the importance of referral to specialized departments and timing. The use of new technologies should be widespread.

Campaign to Increase Awareness of Oral Cancer Risk Factors Among Preadolescents.

Oral squamous cell carcinoma (OSCC) represents one of the most common but scarcely known malignancies worldwide. The etiology of OSCC is strongly related to lifestyle habits and behavior, especially tobacco smoking and alcohol abuse. The mean age of individuals who start smoking and drinking alcohol is decreasing; thus, the aim of our campaign was to test the awareness and increase knowledge of oral cancer and its risk factors among young preadolescents. Six schools with 460 students aged 12-14 years were included in the campaign. A lecture about carcinogenesis and oral cancer was provided. Anonymous questionnaires were submitted to the students before and after the lecture, to test their knowledge, awareness, and understanding. Before the lecture, the students showed very little awareness of oral cancer (26.8%), although almost all of them identified tobacco smoking as a risk factor (92.2%). After the lecture, the students showed a significant understanding of the provided information, thus increasing their awareness. On scales of 1-10, the students rated the appropriateness of the campaign at 8.9 and their overall appreciation at 8.7. Social campaigns, especially among young students, seem to be appreciated and may represent a powerful strategy for increasing knowledge about cancer risk factors, especially when they are highly related to lifestyle habits and behavior.
